Description

Technical Field

[0001] The utility model relates to the technical field of screen production, in particular to a positioning device for screen glue removal. Background Art

[0002] A screen is an electrical appliance used to display images and colors, also known as a display screen. In recent years, with the rapid promotion and popularization of smart devices such as mobile phones and tablets, the global screen market has grown and technological innovation has accelerated, and the scale of the industry has continued to increase. From the perspective of product composition, current mobile phone screens, tablet screens, etc. are mostly touch screens, mainly composed of cover glass, touch modules, display modules and other components. However, with the increasing requirements for thin and light digital products, high-definition display, and the increasing maturity of embedded touch technology, the mobile phone screen industry is gradually developing from traditional single-component supply to integrated module production, and the vertical integration trend of the industrial chain is obvious. In the production and processing of the screen, display sealant is needed to bond the components of the screen together to form an integrated structure. In the process of using glue for bonding, there may be glue overflow and glue leakage around the screen. In order not to affect the assembly of subsequent products, these glues need to be removed. The process of screen glue removal is to scrape off the overflowed glue and leaked glue with a tool. The traditional method is to scrape it manually with a handheld tool, but this method is inefficient. Currently, there is a method of scraping glue with a scraper. The staff places the screen at the work station and then performs the scraping operation. However, this method requires more precise positioning. If the positioning is inaccurate, the scraper may easily damage the screen. Manual loading requires a long time to position the screen, which is inefficient. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0024] Reference Figures 1 to 3The utility model provides a positioning device for screen glue removal, comprising: a machine platform 1, a screen positioning mechanism 2 arranged on the machine platform 1, a support frame 11 arranged on the machine platform 1, and a screen transfer mechanism 3 arranged on the support frame 11; the screen positioning mechanism 2 comprises a base assembly 21 arranged on the machine platform 1, a positioning seat 22 arranged on the base assembly 21, a positioning platform 23 arranged on the top of the positioning seat 22, at least one X-axis positioning block 24 arranged on the positioning platform 23, at least one Y-axis positioning block 25 arranged on the positioning platform 23, at least one X-axis positioning assembly 26 arranged on the positioning platform 23 and matching with the X-axis positioning block 24, and at least one Y-axis positioning assembly 27 arranged on the positioning platform 23 and matching with the Y-axis positioning block 25. Specifically, the X-axis positioning block 24, the Y-axis positioning block 25, the X-axis positioning assembly 26, and the Y-axis positioning assembly 27 are arranged around a positioning area, and the screen is placed in the area when being positioned.

[0025] The X-axis positioning assembly 26 and the Y-axis positioning assembly 27 both include a base plate 261 disposed on the positioning platform 23, a positioning drive 262 disposed on the base plate 261, and a pressing member 263 connected to the output end of the positioning drive 262; the positioning drive 262 of the X-axis positioning assembly 26 drives the pressing member 263 to move toward the X-axis positioning block 24, and the positioning drive 262 of the Y-axis positioning assembly 27 drives the pressing member 263 to move toward the Y-axis positioning block 25. In this embodiment, the positioning drive 262 uses a cylinder. Taking the X-axis positioning assembly 26 as an example, after the screen is placed in the positioning area, the positioning drive 262 drives the pressing member 263 to move toward the side of the X-axis positioning block 24, that is, toward the screen, and presses the screen against the X-axis positioning block 24 to complete the X-axis positioning. The same is true for the Y-axis positioning assembly 27, so that the X-axis and Y-axis positioning of the screen are completed.

[0026] The output end of the positioning driving member 262 is connected to a pressing seat 264, the pressing member 263 is connected to the pressing seat 264, and a spring (buried in the pressing seat, not shown in the figure) is connected between the pressing member 263 and the pressing seat 264. The setting of the spring provides a buffer force when the pressing member 263 contacts the screen, avoiding direct hard contact and damaging the screen, thereby improving the yield rate.

[0027] There are two X-axis positioning blocks 24 , and there are two X-axis positioning components 26 ; there is one Y-axis positioning block 25 , and there is one Y-axis positioning component 27 .

[0028] The positioning seat 22 is movably connected to the base assembly 21. The base assembly 21 is also provided with a lifting drive 4 for driving the positioning seat 22 to move in the vertical direction. The output end of the lifting drive 4 is connected to the positioning seat 22 through a connecting member 41. The lifting drive 4 uses a cylinder to drive the positioning seat 22 to move up and down. When the utility model is used, it cooperates with the scraping device to perform the scraping operation. Therefore, after the positioning is completed, the screen transfer device takes away the screen, and the lifting drive 4 drives the positioning seat 22 to move down to avoid a certain space. While facilitating the screen transfer mechanism 3 to transfer the screen, it also avoids affecting the operation process of the scraping device.

[0029] The base assembly 21 is provided with two groups of buffer assemblies 5 along the vertical direction, and the positioning seat 22 is provided with buffer parts corresponding to the buffer assemblies; the buffer assembly 5 includes a buffer seat 51 connected to the base assembly 21, and a buffer 52 arranged on the buffer seat. The arrangement of the buffer assembly 5 can play a buffering role when the positioning seat 22 moves up and down, avoiding hard contact and damaging parts. In this embodiment, the buffer 52 adopts an oil pressure buffer 52.

[0030] The screen transfer mechanism 3 includes an X-axis linear module 31 connected to the support frame 11, a Y-axis linear module 32 connected to the X-axis linear module 31, a Z-axis linear module 33 connected to the Y-axis linear module 32, and a transport assembly 34 for grabbing and transporting the screen connected to the Z-axis linear module 33. The linear modules of the three axes of the screen transfer mechanism 3 cooperate with each other to ensure that the screen is accurately transferred to the desired position. The linear module can use an electric lead screw.

[0031] The transport assembly 34 includes a transport bracket 341 connected to the Z-axis linear module 33, a transport plate 342 connected to the transport bracket 341, and a plurality of vacuum nozzles 343 connected to the transport plate 342. In this embodiment, four vacuum nozzles 343 are provided. In specific implementation, a suitable number of vacuum nozzles 343 can be selected according to the screen to be processed.

[0032] The conveying plate 342 is provided with a plurality of waist-shaped holes 344 for installing the vacuum suction nozzle 343. In this embodiment, the waist-shaped holes 344 are arranged along the X-axis direction. Since the waist-shaped holes 344 have a certain length, the vacuum suction nozzle 343 can flexibly adjust the position to facilitate adapting to different types of screens.

[0033] The base assembly 21 includes a base 211, a fixing plate 212 vertically arranged on the base 211, and a guide rail group 213 for connecting the positioning seat 22 is arranged on the side of the fixing plate 212. The guide rail group 213 makes the movement of the positioning seat 22 more stable.

[0034] When working, the utility model needs to be used in conjunction with a scraping device. First, the loading device (such as a conveyor belt) transports the screen to a position corresponding to the screen transfer mechanism 3. The screen transfer mechanism 3 grabs the screen and moves it to the positioning platform 23 and then puts it down. The X-axis positioning component 26 and the Y-axis positioning component 27 cooperate to position the screen. After the positioning is completed, the screen transfer mechanism 3 grabs the screen again and transfers it to the scraping station of the scraping device for scraping. Since the path of the screen transfer mechanism 3 is preset, after the screen is positioned, the screen transfer mechanism 3 grabs the screen at the set position, and the screen can be accurately transferred and placed at the predetermined scraping station without offset, ensuring the accuracy of the position.

[0035] The utility model is provided with a screen positioning mechanism 2, and under the action of the positioning component and the positioning block, the screen can be quickly positioned. At the same time, with the cooperation of the screen transfer mechanism 3, the product can be accurately placed at the glue scraping station along the set path, thereby ensuring the accuracy of the product position during the glue scraping process, thereby ensuring the glue scraping effect and the yield rate. The entire process does not require human intervention and basically realizes automation. The overall positioning and transfer process is fast and convenient, and the production efficiency is improved.
